* \section compile_lcd Compiling Raven LCD Driver
*
* Raven LCD Driver can be compiled on the following platforms:
* The Raven LCD Driver is located in /platforms/avr-ravenlcd but it is not a contiki platform.
* $make TARGET=avr-ravenlcd will not work! Build it using the AVR Studio project and WinAVR or
* in Linux/Windows cmd/Cygwin $make in that directory. The AVR Studio dependency folder will confuse
* additional makes, use $make CYG=1 to bypass /dep creation or do $rm -R dep as needed.
* The .h file dependencies will be lost, so also $make CYG=1 clean after modifying any of those.
*
* -# <b>WinAvr + AVR Studio (AVR-GCC).</b> The @b ravenlcd_3290.aps file is used by AVR
* Studio. If you have WinAVR and AVR Studio installed, ravenlcd can be
* compiled and developed using free tools. The Makefile.avr-ravenlcd is not
* used with AVR Studio.
* -# <b>AVR-GCC on Linux.</b> The <b>Makefile.avr-ravenlcd</b> file is to be used for Linux.
* Be sure you have a recent toolchain installed, including patches
* required for GCC/avr-libc to recognize new devices. The avr-libc
* webpage includes a concise guide on how to patch and build the AVR
* toolchain.

* The Raven LCD (3290p device) requires the proper fuse settings to function
* properly. These settings have been summarized below:

* \section sleep_lcd Sleep and Doze
* -# The Raven draws 27 milliamps when the 3290p and 1284p are both running and the RF230 in receive mode.
* -# Sleeping the 3290p and LCD display drops this to 21 ma with no loss in contiki functionality.
* -# The RF230 radio draws 15.5/16.5/7.8/1.5/0.02 ma in Rx/Tx/PLL_ON/TRX_OFF/SLEEP states.
* It is controlled by contiki on the 1284p according to the selected MAC power protocols to obtain the
* bulk of power savings; however the 3290p menu can tell it to sleep unconditionally or in a doze cycle.
* -# Unconditional SLEEP requires pushing the joystick button for wakeup. Once awake the 3290p sends
* SEND_WAKE commands to the 1284p until it responds with a REPORT_WAKE. "WAIT 1284p" is displayed during this time.
* Current draw is 40 microamps.
* -# As configured, doze sleeps the 3290p for 5 seconds after telling 1284p to sleep for 4 seconds. The 3290p
* wakes briefly to send temperature and voltage to the 1284p (which should be awake at this time), then tells it to
* sleep again. Thus the 1284p will be active 20% of the time, although it may ignore the command to sleep
* if there are active TCP connections. The 3290p energy usage is essentially zero in this mode; total savings will
* depend on actual 1284p wake time and radio usage. Alter the timings as desired, or comment out the 1284p sleep
* command to shut down only the 3290p in doze mode.
